TECHNICAL FIELD OF THE INVENTION

The invention relates to novel biphenyloxazolines, to processes for their preparation and to the use of the biphenyloxazolines for controlling animal pests.

BACKGROUND OF THE INVENTION

It is known that certain biphenyloxazolines have insecticidal and acaricidal activity, for example the compounds 2-(2,6-difluorophenyl)-4-(3′-chloro-4′-(1,1,2,2-tetrafluoroethoxy)-biphenyl-4)-2-oxazoline (EP-A-0 696 584) and 2-(2,6-difluorophenyl)-4-(3′-chloro-4′-methylbiphenyl-4)-2-oxazoline (EP-A-0 432 661).

However, the efficacy and/or the duration of action of these known compounds, in particular against certain organisms or at low application concentrations, is not entirely satisfactory in all areas of use.

A mixture with other known active compounds, such as herbicides, or with fertilizers and growth-regulators is also possible.

The active compounds according to the invention can furthermore be present in their commercially available formulations and in the use forms, prepared from these formulations, as a mixture with synergistic agents. Synergistic agents are compounds which increase the action of the active compounds, without it being necessary for the synergistic agent added to be active itself.

The active compound content of the use forms prepared from the commercially available formulations can vary within wide limits. The active compound concentration of the use forms can be from 0.0000001 to 95% by weight of active compound, preferably between 0.0001 and 1% by weight.

The compounds are employed in a customary manner appropriate for the use forms.

When used against hygiene and stored-product pests, the active compound has an excellent residual action on wood and clay as well as a good stability to alkali on limed substrates.

The active compounds according to the invention are not only active against plant, hygiene and stored-product pests, but also, in the veterinary medicine sector, against animal parasites (ectoparasites), such as ixodid ticks, argasid ticks, scab mites, trombiculid mites, flies (stinging and sucking), parasitic fly larvae, lice, hair lice, bird lice and fleas.

The active compounds of the formula (I) according to the invention are also suitable for controlling arthropods which attack agricultural livestock, such as, for example, cattle, sheep, goats, horses, pigs, donkeys, camels, buffalo, rabbits, chickens, turkeys, ducks, geese, honey bees, other domestic animals, such as, for example, dogs, cats, caged birds, aquarium fish, and so-called experimental animals, such as, for example, hamsters, guineapigs, rats and mice. By controlling these arthropods, it is intended to reduce deaths and decreased performances (in meat, milk, wool, hides, eggs, honey and the like), so that more economical and simpler animal keeping is made possible by using the active compounds according to the invention.

In the veterinary sector, the active compounds according to the invention are used in a known manner by enteral administration, for example in the form of tablets, capsules, drinks, drenches, granules, pastes, boluses, the feed-through method, suppositories, by parenteral administration, such as, for example, by means of injections (intramuscular, subcutaneous, intravenous, intraperitoneal and the like), implants, by nasal administration, by dermal administration, for example in the form of dipping or bathing, spraying, pouring-on and spotting-on, washing, dusting, and with the aid of shaped articles which comprise active compound, such as collars, ear tags, tail marks, limb bands, halters, marking devices and the like.

When administered to livestock, poultry, domestic animals and the like, the active compounds of the formula (I) can be used as formulations (for example powders, emulsions, flowables) which comprise the active compounds in an amount of 1 to 80% by weight, either directly or after dilution by a factor of 100 to 10,000, or they may be used in the form of a chemical bath.

Furthermore, it has been found that the compounds of the formula (I) according to the invention have a potent insecticidal action against insects which destroy industrial materials.

The following insects may be mentioned by way of preferred examples but without any limitation:

Beetles, such as Hylotrupes bajulus, Chlorophorus pilosis, Anobium punctatum, Xestobium rufovillosum, Ptilinus pecticornis, Dendrobium pertinex, Ernobius mollis, Priobium carpini, Lyctus brunneus, Lyctus africanus, Lyctus planicollis, Lyctus linearis, Lyctus pubescens, Trogoxylon aequale, Minthes rugicollis, Xyleborus spec.

Bristletails, such as Lepisma saccharina.

Industrial materials are to be understood as meaning, in the present context, non-live materials, such as, preferably, synthetic materials, glues, sizes, paper and board, leather, wood and timber products, and paint.

The materials to be very particularly preferably protected against attack by insects are wood and timber products.

Wood and timber products which can be protected by the composition according to the invention or mixtures comprising such a composition are to be understood as meaning, for example, construction timber, wooden beams, railway sleepers, bridge components, jetties, wooden vehicles, boxes, pallets, containers, telephone poles, wood lagging, windows and doors made of wood, plywood, particle board, joiner's articles, or wood products which, quite generally, are used in the construction of houses or in joinery.

The active compounds can be used as such, in the form of concentrates or generally customary formulations, such as powders, granules, solutions, suspensions, emulsions or pastes.

The formulations mentioned can be prepared in a manner known per se, for example by mixing the active compounds with at least one solvent or diluent, emulsifier, dispersant and/or binder or fixative, water repellant, if appropriate desiccants and UV stabilizers and, if appropriate, colorants and pigments and other processing auxiliaries.

The insecticidal compositions or concentrates used for the protection of wood and wooden materials comprise the active compound according to the invention at a concentration of 0.0001 to 95% by weight, in particular 0.001 to 60% by weight.

The amount of the compositions or concentrates employed depends on the species and the occurrence of the insects and on the medium. The optimum rate of application can be determined upon use in each case by test series. However, in general, it suffices to employ 0.0001 to 20% by weight, preferably 0.001 to 10% by weight, of the active compound, based on the material to be protected.

The solvent and/or diluent used is an organochemical solvent or solvent mixture and/or an oily or oil-type organochemical solvent or solvent mixture of low volatility and/or a polar organochemical solvent or solvent mixture and/or water and, if appropriate, an emulsifier and/or wetting agent.

Organochemical solvents which are preferably employed are oily or oil-like solvents having an evaporation number of above 35 and a flashpoint of above 30 C., preferably above 45 C.; Substances which are used as such oily and oil-like solvents which have low volatility and are insoluble in water are suitable mineral oils or their aromatic fractions, or mineral-oil-containing solvent mixtures, preferably white spirit, petroleum and/or alkyl-benzene.

Substances which are advantageously used are mineral oils with a boiling range of 170 to 220 C., white spirit with a boiling range of 170 to 220 C., spindle oil with a boiling range of 250 to 350 C., petroleum or aromatics of boiling range of 160 to 280 C., essence of turpentine and the like.

In a preferred embodiment, liquid aliphatic hydrocarbons with a boiling range of 180 to 210 C. or high-boiling mixtures of aromatic and aliphatic hydrocarbons with a boiling range of 180 to 220 C. and/or spindle oil and/or monochloronaphthalene, preferably ∀-monochloronaphthalene, are used.

The organic oily or oil-like solvents of low volatility and having an evaporation number of above 35 and a flashpoint of above 30 C., preferably above 45 C., can be partially replaced by organochemical solvents of high or medium volatility, with the proviso that the solvent mixture also has an evaporation number of above 35 and a flashpoint of above 30 C., preferably above 45 C., and that the insecticide/fungicide mixture is soluble or emulsifiable in this solvent mixture.

In a preferred embodiment, part of the organochemical solvent or solvent mixture is replaced by an aliphatic polar organochemical solvent or solvent mixture. Substances which are preferably used are aliphatic organochemical solvents having hydroxyl and/or ester and/or ether groups, such as, for example, glycol ethers, esters and the like.

The organochemical binders used within the scope of the present invention are the synthetic resins and/or binding drying oils which are known per se and can be diluted with water and/or are soluble or dispersible or emulsifiable in the organochemical solvents employed, in particular binders composed of; or comprising, an acrylate resin, a vinyl resin, for example polyvinyl acetate, polyester resin, polycondensation or polyaddition resin, polyurethane resin, alkyd resin or modified alkyd resin, phenol resin, hydrocarbon resin, such as indene/coumarone resin, silicone resin, drying vegetable and/or drying oils and/or physically drying binders based on a natural and/or synthetic resin.

The synthetic resin used as the binder can be employed in the form of an emulsion, dispersion or solution. Up to 10% by weight of bitumen or bituminous substances can also be used as binder. In addition, colorants, pigments, water repellants, odour-masking substances and inhibitors or anticorrosives known per se and the like can also be employed.

The composition or the concentrate preferably comprises, in accordance with the invention, at least one alkyd resin or modified alkyd resin and/or a drying vegetable oil as the organochemical binder. Preferably used according to the invention are alkyd resins with an oil content of over 45% by weight, preferably 50 to 68% by weight.

All or some of the abovementioned binder can be replaced by a fixative (mixture) or a plasticizer (mixture). These additives are intended to prevent volatilization of the active compounds and crystallization or precipitation. They preferably replace 0.01 to 30% of the binder (based on 100% of binder employed).

The plasticizers are from the chemical classes of the phthalic esters, such as dibutyl phthalate, dioctyl phthalate or benzylbutyl phthalate, the phosphoric esters, such as tributyl phosphate, the adipic esters, such as di-(2-ethylhexyl) adipate, the stearates, such as butyl stearate or amyl stearate, the oleates, such as butyl oleate, the glycerol ethers or relatively high-molecular-weight glycol ethers, glycerol esters and p-toluenesulphonic esters.

Fixatives are chemically based on polyvinyl alkyl ethers, such as, for example, polyvinyl methyl ether, or ketones, such as benzophenone or ethylenebenzophenone.

Particularly suitable as a solvent or diluent is also water, if appropriate as a mixture with one or more of the abovementioned organochemical solvents or diluents, emulsifiers and dispersants.

Particularly effective protection of wood is achieved by large-scale industrial impregnation processes, for example vacuum, double-vacuum or pressure processes.

If appropriate, the ready-to-use compositions can additionally comprise other insecticides and, if appropriate, additionally one or more fungicides.

Suitable additional components which may be admixed are, preferably, the insecticides and fungicides mentioned in WO 94/29 268. The compounds mentioned in that document are expressly incorporated into the present application by reference.

Very particularly preferred components which may be admixed are insecticides, such as chlorpyrifos, phoxim, silafluofin, alphamethrin, cyfluthrin, cypermethrin, deltamethrin, permethrin, imidacloprid, NI-25, flufenoxuron, hexaflumuron and triflumuron, and fungicides, such as epoxyconazole, hexaconazole, azaconazole, propiconazole, tebuconazole, cyproconazole, metconazole, imazalil, diclofluanid, tolylfluanid, 3-iodo-2propinyl-butyl carbamate, N-octyl-isothiazolin-3-one and 4,5-dichloro-N-octylisothiazolin-3-one.

Preparation of Starting Materials

Example (VI-1)

2,6-Difluoro-N-[2-chloro-1-(4-(4-acetoxy-3-n-propylphenyl)phenyl)ethyl]-benzamide

At 0° C., 28.5 g (0.215 mol) of aluminium chloride are added a little at a time with stirring to a solution of 14.9 g (59 mmol) of 4-acetoxy-3-n-propylbiphenyl and 16.2 g (65 mmol) of 2,6-difluoro-N-[2-chloro-1-methoxyethyl]-benzamide in 100 ml of dichloromethane. The mixture is stirred for 30 minutes, a further 4 g (30 mmol) of aluminium chloride are added and the mixture is stirred for a further 2 hours at 0° C. The reaction mixture is poured onto ice, the product is extracted with dichloromethane and the organic phase is concentrated under reduced pressure. 27 g of a resinous crude product (log p=3.92, pH 2.3) are obtained and used for further reactions without any further purification (˜100% crude yield).

Example (V-2)

2.6-Difluoro-N-[2-chloro-1-(4-(4-ethoxycarbonyl-3,5-dichlorophenyl)phenyl)ethyl]-benzamide

At 0° C., a solution of 32.5 g (0.13 mol) of 2,6-difluoro-N-[2-chloro-1-methoxyethyl]-benzamide and 40 g (0.13 mol) of (2,6-dichloro-4-phenyl)phenylethyl carbonate in 100 ml of dichloromethane are added to 500 ml of hydrofluoric acid. The mixture is stirred overnight at 14° C., the hydrofluoric acid is removed under reduced pressure and the residue is taken up in dichloromethane and washed with water. The organic phase is separated off and concentrated under reduced pressure using a rotary evaporator. 54 g of 2,6-difluoro-N-[2-chloro-1-(4-(4-ethoxycarbonyl-3,5-dichlorophenyl)phenyl)ethyl]-benzamide are obtained as a viscous resin (log p (pH 2.3): 4.17). The product is used for further reactions without any further purification.

Example (II-1)

2-(2,6-Difluorophenyl)-4-(4-(4-hydroxy-3-n-propylphenyl)phenyl)-2-oxazoline

At −10° C., a solution of 3.7 g (92 mmol) of sodium hydroxide in 10 ml of water is added dropwise with stirring to a solution of 27 g (57 mmol) of 2,6-difluoro-N-[2-chloro-1-(4-(4-acetoxy-3-n-propylphenyl)phenyl)ethyl]-benzamide in 150 ml of dimethylformamide. The mixture is stirred overnight, 43 ml of a 25% strength solution of ammonia are added and the mixture is stirred overnight. The reaction mixture is then poured onto ice-water and extracted repeatedly with ethyl acetate. The combined ethyl acetate extracts are dried over MgSO₄ and concentrated under reduced pressure.

21 g of crude product (1 g p=3.77, pH=7.5) are obtained (crude yield 93.7%). A small sample of the crude product, stirred with petroleum ether/chloroform, gave a product of Mp. 210-215° C.

Example (II-30)
